We are developing an automated SimpleSFTPClient process that uses public key authentication when establishing an SSH2 connection with the SFTP server.

We are attempting to load a private key into an instance of the ElSSHKey class using the LoadPrivateKey method. When using this 3DES-CFB private key, we keep getting the return code of 3338 ("PEM algorithm is unsupported"). If we use a different private key generated with OpenSSH using 3DES-CBC, the key loads fine with a return code of 0.

My question is, is there some property that I am missing to specify that the private key we intend to use is 3DES-CFB, or is CFB truly not supported for this type of task?

SecureBlackbox does not support 3DES-CFB algorithm, sorry. Please convert your key to one of supported formats (PEM/3DES-CBC, IETF, raw, Putty etc.) beforing loading it into TElSSHKey.
